capable of being made at less expense'than heretofore.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

lVith the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in front elevation a deviceconstructed in accordance with the invention, parts bein broken away,and parts being in section; Flgure 2 is top plan; Figure 3 is an endelevation; Figure 4 1s a fragmental front elevation, with the box dottedin place, as it will appear during the final step in completion of thebox; Figure 5 is a fragmental horizontal section; Figure 6 is afragmental rear elevation.

In carrying out the invention, there is provided a frame, including endmembers which are 'L-shaped, each end member comprising a verticalstandard .1, provided at its lower end with a forwardly extendedhorizontal foot 2, disposed at right angle to the standard. Verticalabutments 3 are located at the outer edge of each standard, and areconnected to the standards and to the feet 2. The standards 1 areprovided at their upper ends with rearwardly extended horizontal heads4. Owing to the specific L shape of the end members, as shown clearly inFigure 3, the cost of the material is reduced greatly, and it is notnecessary to provide expensive 1931. Serial No. 539,911.

tables or complicated frames of the working parts. j r

The end members areheld in place by longitudinally adjustable ties 5,which'may be bolts, with nuts on them, the bolts being mounted in theheads 4,as Figures-2 and 3 will show. The longitudinally adjustable ties5 adaptthe machine for boxes of different sizes, and they also enablethe endmembers of the frame to be adjusted to parallel relation, tofacilitate the making of the boxes, as will be disclosed hereinafter.Onthe outer edges of the heads 4 there are upstanding plate-like wings6, having bevelled forward ends 7 which facilitate the introduction ofthe material into the machine. j

At their rear ends, the wings 6 have outwardly extended flanges 8. Inthe inner surfaces of the wings 6, there are'vertical seats 9 in whichretainers 10 are Vertically adjustable; The retainers 10 extend upwardlyabove the upper'edgesof the wings 6, and haveholesll arranged invertical lines, as shown in Figure 3 the holes being adapted to securingelements 12, suchas bolts, mounted in the wings 6 and permitting theaforesaid vertical adjustment of the retainers 10.

The machine comprises a back, andethe back includes a bar 1 1, havingslots 15 in it ends, these slots being adapted to receive holdingdevices 16,such as" screws (Figure 5), mounted in thefianges 8 of thewings 6; The back bar 14 is provided with arms 17 extended upwardlyabove the back'bar 14, and having shoulders18 which rest on theupperedge of the back bar. The arms 17 are connectedto the back bar 14by securingmembers 1-9.

Clamps 20 cooperate with the wingsi6 in holding certain parts of thebox, as will be 7 described hereinafter. The clamps 20 are connected byhinges 21 to the inner edges of the heads 4. Springs 22 arecontain'ed-inthe hinges 21 and tend to swingthe clamps 20 toward the wings 6, so asto hold the box-parts,

in the construction of the box; The clamps. 20 have upper inwardlyinclined fingers 23. On the forward edges of the clamps 20ther e areinwardly extended fingers24. Under the action ofthe springs 22, theclamps '20 swing for the support f ted position of Figure 3, and 7 sideis fixed in place.

inwardly to the position of Figure i, and then the movable leaves of thehinges 21 engage the heads 4, as shown at 100 in Figure 4, and hold theclamps with the fingers 23 slanting downwardly toward the wings 6, andwith the fingers 24 slanting backwardly toward the wings, tofacilitatethe introduction of the material between the clamps and the wings.

In practical operation, the boxends 25, are

' set up on the heads 4 and are heldbythe spring clamps 20 against theretainers 10.

Owing to the positions assumed by the'fingers 24 and 23 ofthe clamps 20with respect to the wings 6 in Figure 4, the box ends can be slidto-place either horizontally a-ndback- 'wardly or vertically anddownwardly, and

abut against the back bar 145.v The bottom 26 of the box is laid on theupper edges of the ends 25 and is held against horizontal move ment bythe retainers '10 and the arms 17.

The cleats 27 are placed on the bottom 26 (if cleatsare used),inengagement with the retainers ,10.0f Figure 4., After the cleats 27'are nailed, the partially completed box is taken off the heads 4 and issetup against the standardsl, on the feet 2, between the abutments 3,and the side 28 is nailed to place.

nally adjustable to permit the end members to be adjusted toward andawayfrom each other, retainers on thewings and extending upwardly'above thewings, and means for holding the retainers in vertically adjustedpositions. 1

A box-form comprising end members having approximately horizontalheads, upstanding wings at the outer edges of the heads, a backconnecting the rear portions ofthe wings and clamps hinged to the inneredges of the heads, the clamps being provided'at their upper ends withinwardly-inclined fingers, and being provided on their forward edgeswith inwardly-inclined 7 fingers, the clamps swinging outwardly 1 towardthe wings, until theclamps engage the, heads, and

stop, with the first-specified fingersslanting downwardly toward thewings, andgwith the second-specified lingers slanting backwardly towardthe wings. e In testimony that as my own, I have hereto affixed mysignature,
